The correct answer is images and diagrams.

Explanation:

According to Jerome Bruner's theory of cognitive development, learners construct knowledge through three distinct modes of representation:

1. Enactive Mode (Action-based): Learning through direct physical manipulation and hands-on activities.

2. Iconic Mode (Image-based): Learning through visual representations, such as images, diagrams, pictures, and graphs. Information is stored visually in the form of mental pictures.

3. Symbolic Mode (Language-based): Learning through abstract symbols, language, code, or mathematical notation.

Therefore, the iconic mode of learning is specifically based on the system of using images and diagrams.
